Abandoned oil and gas wells, known as “zombie wells,” pose significant environmental and safety risks across the United States. An estimated 3.5 million wells are scattered nationwide, with many leaking hazardous substances such as methane, benzene, and hydrogen sulfide. Communities near these wells face threats ranging from water contamination to catastrophic explosions. In West Texas, rancher Laura Briggs’ property is marred by leaking orphan wells, highlighting regulatory failures and the immense challenges of managing abandoned sites.

An ABC News investigation tested 76 abandoned wells across five states, discovering leaks in 40 of them. Leaking wells were found in a variety of locations, from Kansas farms to Los Angeles hiking trails, emitting combustible gases and toxic chemicals. Offshore, seven out of ten wells tested near Houston were leaking. The findings underscore the scope of the problem, with abandoned wells emitting potent greenhouse gases and carcinogens that threaten public health and accelerate climate change.

The cost of plugging orphan wells is staggering, with estimates exceeding $250 billion nationwide. States like Texas face mounting pressure to address the issue, yet available funds cover only a fraction of the need. Current bonding requirements for oil companies often fall short, leaving taxpayers to foot the bill. Attempts to reform regulations face resistance from industry groups, perpetuating a cycle where neglected wells remain unaddressed, endangering both communities and ecosystems.

Thousands of abandoned wells lie buried beneath U.S. cities, including Los Angeles, where methane vents disguised as fence posts reveal the hidden danger. Residents of neighborhoods like Vista Hermosa face elevated health risks, with illnesses linked to long-term exposure to leaking wells. Along hiking trails in El Escorpion Park, leaking wells continue to emit dangerous levels of gas. Regulatory agencies acknowledge the risks and promise action, but progress remains slow, leaving residents and the environment vulnerable.
